tests: test the test framework more thoroughly

Add 5 new full test suite runs each with a different number of
passing/failing/broken/fixed tests, in order to ensure that the
correct exit code and output are generated in each case.  As before,
these are run in a subdirectory to avoid disrupting the metrics for
the parent tests.
